Thread: 98 Regal GS bad tranny.

So how hard is it to swap the diff? And would I still have to recalibrate the pcm if I swap the diff? Also no luck with craigslist in my area. Every gtp or gs has a broken tranny but the engine is still good. I don't have the money to get the transmission that's in it rebuilt either.

Never having done a dif swap myself, cant really tell ya too much. Theres a thread on how to do it around here somewhere.....

If you swap the dif, no you wont have to program it.
